生活在机构环境中的幼儿通常在社会、身体和认知功能方面表现出一系列缺陷。虽然在一些调查中对收容后儿童的皮质醇日产量进行了调查，但对继续生活在收容机构的儿童的研究有限。在这项研究中，我们评估了居住在俄罗斯的73名儿童的起床和睡前皮质醇，其中52名由机构抚养(n=31)，21名家庭抚养(n=18)。在时间1和时间2中，制度养育的孩子比家庭养育的孩子对睡前倾斜度的觉醒更迟钝，睡前皮质醇水平显著高于家庭养育的孩子。这些发现突显了机构护理对儿童发育中神经内分泌调节的有害影响。
Young children living in institutional settings often show a range of deficits in social, physical, and cognitive functioning. Whereas the diurnal production of cortisol has been examined among post-institutionalized children in a number of investigations, studies of children continuing to live in institutions are limited. In this study, we assessed wake-up and bedtime cortisol among 73 children living in Russia, with 52 institutionally-reared (n = 31 at time 2), and 21 family-reared (n = 18 at time 2). Institutionally-reared children showed a blunter wake-up to bedtime slope than family-reared children at both time 1 and time 2, with significantly higher cortisol levels at bedtime. These findings highlight the deleterious effects of institutional care on children's developing neuroendocrine regulation.
